Abstract
A field experiment was conducted to determine the growth and yield of watermelon production under organic and inorganic nutrient management. The different treatments applied were: T1 - Control No fertilizer, T2 - Recommended Rate of Organic Fertilizer (RROF), T3 - Recommended Rate of Inorganic Fertilizer, T4 - 50% RRIF + 50% RROF, T5 - 75% RRIF +25% RROF and T6 - 25% RRIF + 75% RROF.
Results of the experiment reveled that watermelon plant with the longest vine, most number of leaves, largest fruits, sweetest fruits, highest yield and highest return on income were obtained from 75% recommended rate of inorganic fertilizer (RRIF) + 25% recommended rate of organic fertilizer (RROF) compared to other treatments evaluated.
